Wiggle stepper

ABSTRACT

A wiggle stepper includes a base member, an adjust seat mounted on the base member, two platforms respectively pivotally mounted to the base member, a connector for connecting the platform and a cylinder that is mounted between the platform and the base member. Each platform is moved upwardly and downward, and wiggled obliquely to prevent the moving route of the platform from forming a dead space for user to smoothly operate the two platforms. The user can adjust the position of the adjust seat for adjusting the tension from the adjust seat according to the physical strength of the user.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a stepper, and more particularly to awiggle stepper.

2. Description of Related Art

A conventional stepper in accordance with the prior art shown in FIG. 9comprises a base member (60) and two platforms (61) each with onepivotally mounted to the base member (60). Two cylinders (62) eachmounted between a corresponding one of the two platforms (61) and thebase member (60) for providing damping to the two platforms (61) whenthe user steps thereon.

The conventional stepper only provides an exercise to the user's legs byrepeatedly swinging up and down. As a result, the user may feel that isa boring exercise and gradually reduce the use frequency of theconventional stepper. In addition, the damping from the cylinders (62)can not be adjusted according to the purpose of the user. Consequently,the using scope is limited.

The present invention has arisen to mitigate and/or obviate thedisadvantages of the conventional stepper.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide an improvedstepper that is a wiggle stepper.

To achieve the objective, the wiggle stepper in accordance with thepresent invention comprises a a base member, an adjust seat mounted onthe base member, two platforms respectively pivotally mounted to thebase member, a connector for connecting the platform and a cylinder thatis mounted between the platform and the base member. Each platform ismoved upwardly and downward, and wiggled obliquely to prevent the movingroute of the platform from forming a dead space for user to smoothlyoperate the two platforms. The user can adjust the position of theadjust seat for adjusting the tension from the adjust seat according tothe physical strength of the user.

Further benefits and advantages of the present invention will becomeapparent after a careful reading of the detailed description withappropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-7, a wiggle stepperin accordance with the present invention comprises a base member (10),an adjust seat (20) mounted on the base member (10), two platforms (30)respectively pivotally mounted to the base member (10), a connector (40)for connecting the platform (30) and a cylinder (50) that is mountedbetween the platform (30) and the base member (10).

The base member (10) is H-shaped and has a seat (11) mounted on a frontportion of the base member (10). The seat (11) includes a plate (111)perpendicularly upwardly secured on a front end of the base member (10)and two cubic posts (112) mounted on a top of the plate (111). The twocubic posts (112) are adjacent and parallel to each other, and extendtoward a rear end of the base member (10) to define a V-shaped groove(12) under the two cubic posts (112). Each cubic post (112) includes afront end having a pivot (13) upwardly and outwardly mounted thereon. Abolt (14) is screwed through the plate (11) from the front end of thebase member (10) and a pin (15) is laterally secured on a middle portionof the base member (10).

The adjust seat (20) includes a U-shaped frame (22) with one endpivotally connected to the bolt (14) and a guiding portion (21) formedon the top of the frame (22) such that the adjust seat (20) can beslidably mounted under the two cubic posts (112). The guiding portion(21) has a shape corresponding to that of the groove (12) under the twocubic posts (112). A shaft (221) is longitudinally secured between abottom of the frame (22) and the guiding portion (21) for pivotallymounted a damping wheel (23) within the adjust seat (20).

Each platform (30) has a first end sleeved on a corresponding one of thetwo pivots (13). A crank (31) is formed on a front section of each ofthe two platforms (30). A cable (32) has two opposite ends respectivelysecured on the two cranks (31) and coiled on the damping wheel (23) tomake the two platforms (30) moved contrary relative to each other. Eachcrank (31) has a connecting seat (33) mounted thereon for connecting tothe connector (40).

The connector (40) has a first end having a first pivot hole (401)defined therein and a second end having a second pivot hole (402)defined therein. The first pivot hole (401) and the second pivot hole(402) perpendicularly correspond to each other. The first end of theconnector (40) is pivotally received in the connecting seat (33) by apin (not numbered) extending through the connecting seat (33) and thefirst pivot hole (401) in the first end of the connector (40). AnH-shaped linkage (41) has a first end pivotally mounted to the secondend of the connector (40) due to the second pivot hole (402). A cylinder(50) has a first end pivotally connected to a second end of the linkage(41) and a second end pivotally mounted to a corresponding end of thepin (15). The cylinder (50) can absorb the gravity from thecorresponding platform (30) when the user steps thereon.

The platform (30) is moved upwardly and downward, and wiggled obliquelydue to the angle of the pivot (13). In addition, the linkage (41) isupwardly and downward moved to prevent the moving route of the platform(30) from forming a dead space for user to smoothly operate the twoplatforms (30). Furthermore, the user can adjust the position of theadjust seat (20) for adjusting the tension of the cable (32) accordingto the physical strength of the user.

Although the invention has been explained in relation to its preferredembodiment, it is to be understood that many other possiblemodifications and variations can be made without departing from thespirit and scope of the invention as hereinafter claimed.
